Adjusting or turning off TM is not going to cause a failure , your new found ability to put the power to the ground and rock and roll will

there is an abuse mode (which is different that TC or AH. Although there's code in the PCM for the Abuse Mode, I've never known a person to meet all the parameters necessary for that to be engaged.
And actually is's not for "abuse", but more from too hot operating temps - or oil temps too high. It's more a "self-preservation" mode than an abuse mode.

A 2000 auto also has a 70% wot setting from the factory , that will also be address by the tuner .

Let me tell you what happened to me the other day, first of all I have a 02 a4 Corsa Catbacks BPP air induction 3:42's and a Predator HP tune. the only other thing I did with the predator after the tune was increase the shift pressures 5%.I took off from a stop in 3rd at about 70% throttle.it hit second gear, the back end broke loose, crossed centre line, scared the sh-t out of me for a second then I could't stop smiling!! Moral of the story be careful what you wish for, you don't need to scew with TM.

The shifter was in 3rd. The transmission still starts in 1st goes to 2nd then 3rd and so on. When it shifted from 1st to 2nd thats when it got exciting

the trani in a C5 is the weakest link in the drive train.GM put TM in to "protect" the trani since its not designed to handle all the torque the engine can generate.The torque management tables can be adjusted to increase the % of torque delivered to the rear wheels. Its not a good idea to totally disable torque management unless you'd like to get to know the guys at RM transmissions.

If you only has efi live I could change all that stuff for ya and send you the tune over email. I didn't delete the torque management but did reduce it. I done alot of other small things also on mine. seemed to help alot.

Also, as stated, it's not an on-off thing. The level of TM can be adjusted via a set of parameters. If you put in a heavier built tranny you could tune out say 75% of the TM.

The trans in the Vette will handle the motor just fime. Look how many C5's have over 100,000 miles on them with no trans trouble, It is when you start over powering the motor that you have troubles, That is why there are high performance trans and diff parts. Almost all newer cars have TM or AM built in the computer, It isn't just GM.

Can you increase shift pressure (line pressure) and still keep the stock torque management settings in place?
I've always been taught that a shift kit actually prolonged the life an automatic transmission. That is, soft shifts build up excess heat. Perhaps it's only the case if the automatic transmission is capable of handling the shock in the first place?
I'd was thinking about purchasing a Predator just to firm up the shifts. If the 'vette can't handle it, then I guess I'll just keep my money.
